Windows 10: [SOLVED] Hard Drives not showing up

So I installed two 500 GB Western Digital Blues yesterday, and they worked fine. But, after a reboot today, they no longer show up. They are in device manager and in my UEFI, but disk management doesn't show it. I reset the bios with no prevail on the issue. Samsung Magician also thinks that I am in RAID mode, so could that be why? I don't think it is because I reset the bios to AHCI. I appreciate any help given. Thanks.

External Hard drives stopped showing up on computer

I have been using my external hard drives (Seagate - small ones, but not USB) for a couple of years. One is only six months only. Today, they stopped showing up on my computer. I hear the ding when I connect them, but they do not show up on my computer
or on file explorer.

What have I done wrong?

Thanks.

the issue?

Please keep us posted for us to assist you further.

 

Yep! That seems to be the issue. Fixed.
